Q

' 'In the accompanying drawings, A refers to a suitably-constructed basewith bearings for a vertical shaft, to which a rotary motion is impartedin any suitable manner, and this thereon, so as toextend slightly beyondthe periphery of a platform B, which is rigidly attached to the verticalshaft. The platform B has attached to its upper face a plurality ofconcentrically disposed valve-trips and a marginal trip 6 to releasegravitating-latches 0 0, carried by a table C, maintained in movableengagement with the shaft. .The platform B is provided about its centerwith a plain surface, thetable O having a depending portion which reststhereon, the table and platform being maintained in frictional en- Thepart of the table beyond its centraldepending portion overlies theconcentric valve-trips. The catches a c alternately engage the stop-bar(4, attached to the'base, and as the platform is turned the trip 6thereon engages one of the catches, releasing it from the stop, so thatthe table and platform may revolve in unison. The arrangement andconstruction of the parts is such that'the table 0 and the mechanismcarried thereby make a half turn or revolution for each full revolutionof the platform-.-

The table C carries supports DD, E E, having bearing-boxes for thetrunnions of cylinders F F and G G, the latter cylinders having pistons.with yokesg g to engage bosses which project from the main cylinders.The outer ends of the. piston-rods'for, the main cylinders areconnectedto yokes H H, hav- 7 ing slide-bars it it, which engageguides attachedtothe cylinders. The piston-rods reciprocate the yokes, to which areconnected molds or glass-gathering means I I. Auxil- TOO iary cylindersJ J are carried by the slidebars it it, the piston-rods of such smallercylinders engaging and actuating means for turning the. molds in thebearings of the yokes, it being desirable to turn the molds from anupright to an inverted position and back again.

The table C has at its center an upwardlyprojecting hollow standard L,the upper end being closed by a suitable packing-box. The standard hasan opening Z, surrounded by a housing L, with stuffing-boxes, so thatthe housing may turn on the standard. Through the standard L there ispassed a pipe M, the upper end entering a box from which extends asupply-pipe M.

The construction shown in Fig. 10 provides means whereby hydraulicpressure may be supplied for operating one or more of the cylinders andair under pressure for forcing the molten glass into a mold or ladle tocharge the same.

The center valves f and f are double valves, inasmuch as the turningplugs are provided with two ways one for admitting pressure to thecylinders G G, the other way communicating with a pipe for conveying airunder pressure into the receptacle for molten glass to force when thereceptacle is closed the charge into the glass gathering device or mold.Pressure, either hydraulic or pneumatic,when admitted into the cylindersG G forces the pistons thereof upward and moves the main cylinders F Ffrom a horizontal to an inclined position, and simultaneouslyairpressure is let into one of the pipes 92 n and passes either into ascoop or into the receptacle, in either case upon the surface of themolten glass to charge the mold. The valves which are supported by thetable C are connected to branch pipes, through which either air or waterunder compression may pass,

the construction of the valves being shown by Fig. 9, such valves beingself-closing by reason of the springs and are operated by arms attachedto the plugs, which arms are moved against the action of the springs bythe segmental trips attached to the rotary platform B.

The ports at one end of the main cylinders are connected by flexibletubing to valves cl cl, The ports at the opposite ends of the smallercylinders J J are similarly connected to the valves 6 e. The doublevalves f f communicate with ports on the trunnions of the cylinders G Gand also, through other ports in the plugs, with pipes 12.12.. Thevalves 2" when opened let pressure into the smaller cylinders J J toproject the pistons thereof, and the valves 71; is when opened admitpres-- sure into the end of the main cylinders to retract the pistonsthereof. The arms on the valves 0 e and z' z" are each on the same are,being equally distant from the center of the table. The valves ff areeach the same distance from the center, but nearer to the center thanthe valves 0 and 2'. The valves (1. Z, (Z, and Z" are each positioned atdifferent distances from the center to be out of line with each otherand with the arms of the other valves.

The concentric trips on the platform 13 may be arranged substantially asshown in Fig 3, there being ten arms for the valves and a like number oftrips on the platform. The valvearms are arranged so that five are oneach side of the table, and the trips are so positioned that six will beon one side and four on the other. Both the trips on the platform andthe arms on the plugs of the valves may be adjusted to advance or retardthe time of contact and the movements of the parts connected therewith.

In the drawings 1 have shown in Fig. 1 the platform B positioned so thatthe trip 6, which releases the latches a c on the table from the stop a,will be to the rear and nearly at right angles to the mold-carryingframes, the latch 0 being in engagement with the stop a. The platform Bturning in the direction indicated by the arrow, the valves on the sideof the table nearest the trip are open to the atmosphere, the mold atthis time being on the glass-blowing machine. ()n the other side orfront of the machine the valvetrips on the platform have passed thevalved, through which pressure passes to the end of the cylinder F nowfarthest from the mold. The valve opens the end of the cylinder Jnearest to the mold to the atmosphere. The central double valve f hasbeen turned, and pressure admitted to the cylinder G rocks or oscillatesthe cylinder F, lowering the mold and closing the receptacle for moltenglass, and when the mold has entered the receptacle air is admitted uponthe surface of the glass to charge the mold. As soon as the mold ischarged the arm of the double valve will have passed its trip and themain cylinder resumes its horizontal position, lifting the mold from thereceptacle. The arm of the valve 1 being ongaged by a trip lets pressureinto the cylinder J, projects its piston-rod, and turns the mold from aninverted to an upright position. A further movement of the platformbrings one of its trips beneath the arm of the valve 1: to retract thepiston of the cylinder F and moves the mold and its supporting-frameinward. A' comparatively short period before the trip 7) engages thecatch on the table a trip on the platform actuates a valve and admitspressure into the cylinder F to retract its piston and remove the moldfrom the tahle of the blowing-machine. After both pistons have beenretracted the trip I; engages and releases the catch from the stop (1.The table now being unrestrained turns with the platform until the otherlatch engages the stop. As the platform turns the trips (Z (1" willengage the arms of the valves (Z and (1', projecting the pistons of thecylinders F FK The trip 6 engages the arm of the valve eto cause aretraction of the piston in the cylinder J' to turn the moldfromanupright to an inverted position. The trip f engages the arm of thedouble valve f, oscillating the cylinder F, lowering the inverted end ofthe mold into thereceptacle and closing the same. Whenthe mold islowered, the frame and wings connected therewith close the receptacleand air passes through the pipe n upon the surface of the molten glass.About the time that the double valvefis tripped the trips d2 and 6Z3will .,ha e.passed the arms of the valves d and d. While the trip f isstill in engagement with the arm of the valve f the trip 0 which haspreviously actuated the valve 6, will, en-, gage the arm of the valve2', admitting pressure to project the piston of the cylinder J to turnthe mold I to an upright position.

The trip actuates the arm of the valve 76 to retract the piston-rod ofthe cylinder F. A considerable time after the piston in. the cylinder Fhas been retracted the trip 70 engages the arm of the valve is to effecta retraction of the piston in the cylinder-F, which moves the mold-1from the blowing-machine. A further movement of the platform brings thetrip 7) under the restraining-latch 0, and the table C turns with theplatform until the op-- posite latch c engages the stop a. .The tablebeing held by the restraining-latch 0, the valves ('5', e, f", 41, andis will'be to the front, the mold marrying frames vbeing retracted. Theplatform turning, the trips OZ. and cliengage .the arms of the valves dand cl. The pistonrrods of L the cylinders 'Fand F being projected placethe-charged'mold on the frame H on the table of the glass-blowingmachine and the empty mold 1 over the receptacle which contains moltenglass. The platform as it turns brings the trip 0 in engagement with thearmof the valve 3', the trip f with the arm of the double valve f, thetripe with the arm of-the valve 71', the trip 70 with the arm. ofthevalve 71: to charge the .mold and bring its support toahorizontal-position. After the mold has been charged and itssupporting-frame. brought to a horizontal position the trip is engagesthe arm of the valve 70 and the mold-supporting frame is retracted toremove the mold from the blowing-machine, after .which the table makes ahalfrevolution toplace a charged mold on the table and to charge themold whichhas beenremoved therefrom.

In operation the mold or glass-gathering makes, one-half of arevolution, such move ments positioning the larger number of the eratedeither by a movement of the mechananism for turning the mold or by airadmitted to a cylinder having a pistonand an attached plunger.

As shown in Fig. 8, a scoop S may be provided to dipmolten. glass fromthe receptacle and carryit over the open end ofthe mold, after which theopen end of the scoop is closed by a cover S and air is let into thescoop to force the charge therefrom into the mold. In each case the moldhas openings leading to the atmosphere to permit the escape of air fromtheimatrices as the charge is forced into the mold. v

The apparatus, with slight modification, may be used to ladle glass froma receptacle to a mold, cup, or other mold-charging device, and meansmay be provided for stopping the rotation of the platform when desired.
